Starting materials: PbO, HI (57% (w/w) in water), H3PO2 (50% (w/w) in water)
Product: yellow plate-like crystals
Description: 5 mmol PbO was dissolved in a solution of 40 mL HI and 5 mL of H3PO2 by sonicating in an ultrasonic bath sonicator for 10 min. The solution is cooled to ∼278 K using an ice−water bath. In this solution, 10 mmol H2N-(CH2)3-OH is added dropwise. The solution is stirred using a magnetic stirrer and heated for 30 min in an oil bath maintained at 383 K. After 30 min, the heating and stirring are stopped, and the solution is kept undisturbed. After 12 hours, the precipitated crystals are separated by filtration with diethyl ether and dried in air.
Method: Diffuse reflectance spectroscopy
Description: The spectrum was recorded using a Shimadzu UV3600 plus UV−vis−NIR spectrophotometer with BaSO4 powder as a reference of 100% reflectance. The reflectance signal is converted to absorbance using the Kubelka−Munk function.
